Input voltage: DC 10.5V-15V (when the battery voltage is lower than 10.5V, the inverter is low voltage protected, when the battery voltage is higher than 15V, the inverter is high voltage protected)
Optional output voltage: AC 110V, AC220V
Starting frequency: 50Hz for 220V model/60Hz for 110V model.
Peak power: 4000W
Rated power: 300W
Output waveform: Modified sine wave.
8 Safety protection functions: Reverse polarity protection, low voltage protection, high voltage protection, overcurrent protection, short circuit protection, over temperature protection, overload protection, internal fuses.

Instruction:
What size inverter do I need? (See the specification plate on the device or tool). We recommend buying a larger model than you think you need (at least 10% to 20% more than your largest load).

Warning:
1. This is a modified sine wave converter, not applicable for devices that work with built-in motors, hair dryers, air conditioners, coffee machines, water pumps, induction cookers, refrigerators, and microwave ovens. Make sure the total rated power of the connected devices is ≤ 400 W.
2. Tighten the positive (+) and negative (—) terminals when the car converter is in use.
3. If the converter is directly connected to the cigarette lighter. The highest output power must be below 150 W. If more than 150 W, it is strongly recommended to use clamps for a battery as the car's cigarette lighter cannot handle power above 150 W.
4. The car converter is suitable for DC12V and not for DC24V and aircraft.
5. Do not leave the inverter in position before starting the car. It is easy to damage the inverter before it is connected to the battery. Turn on the inverter's power switch.
6. It is normal for the inverter to get hot during use. For best results, place the inverter on a flat surface. The workplace must meet the following criteria:
(1) Keep dry, should not let the inverter come into contact with water or other liquids, keep the inverter away from moisture or water.
(2) Cool environment, keep the temperature between 0 degrees Celsius and 40 degrees Celsius. Do not place the inverter next to heat vents or other devices. Try to ensure that the inverter is not directly exposed to sunlight.
